TEMPLE-MEASURING DEVICE.

Specification of Letters Patent.

Patented Mar. 21, 1911.

To all whom it may concern:

Be it known that I, ELIZABETH LEE NERO, a citizen of the United States,residing in the city and county of San Francisco, State of California,have invented new and useful Improvements in Temple-Measuring Devices,of which the following is a specification.

My invention relates to devices for measuring the temple pieces ofspectacles and the object thereof is to provide a simple and efficientdevice by the use of which the length of a temple piece may be correctlyascertained without straightening it out and measuring it on a rule. Iaccomplish this object by the device described herein and illustrated inthe accompanying drawings in which,

Figure l is a perspective view of my improved measuring device, with thetemple piece inserted therein. Fig. 2 is -a central section of the bowend of the device and a side elevation of the remaining portion of thedevice taken from the side opposite of Fig. l, with a temple piece inplace therein. Fig. 3 is a section on the line 8-3 of Fig. 2. Fig. 4 isa side elevation of a temple piece.

I11 the drawings 5 is the crook or head of my measuring devicepreferably provided with a groove 6, which groove is preferably on theinner side thereof. The outer end of this groove preferably terminatesin a pocket 7 in which is received the outer end of the temple piece 8when my device is used for measuring the same, as best illustrated inFig. 2. If desired the groove could be in the side of the device, but itis more convenient for use when the groove is in the inner side of thehead; or the groove could be omitted. The body 9 is provided with ascale 10 on one side thereof, which scale is provided with the usualmarks which designate the ordinary lengths of temple pieces. On theopposite side of the body may be placed a millimeter scale 11 formeasuring pupilary distances.

In the use of my device we will assume that a user has broken one of thetemple pieces of his spectacles and desires to have a new one in placeof it. He goes to an optician equipped with my improved measuringdevice, who takes the uninjured temple piece and places the outer endthereof in the pocket in the head of the measuring device and forces thecrook into the groove in the head and brings the remaining portion intocontact with the body. The end of the temple piece will then comeopposite one of the figures of the scale as shown in Fig. 1, which willimmediately show to the Optician the required length of temple piece tobe used in replacing the broken one. He then goes to his supply depotand selects the temple piece of the required length and puts it into theframe. By this means he has quickly and accurately ascertained theproper length of temple piece, without in any manner affecting the othertemple piece, as must be done without the use of my improved measuringdevice.

Having described my invention what I claim is;

1. A temple piece measuring device comprising a non-sectional body pieceprovided with a scale on one side thereof, and having a curved head,said head having a stop against which the outer end of the bow abutswhen being measured.

2. A temple piece measuring device comprising a body piece provided witha scale on one side thereof, and having a curved head containing agroove, said groove terminating in a pocket at the outer end thereof.

3. A temple piece measuring device comprising a crook having a groove inthe inner side of the head thereof terminating in a pocket in the outerend of the groove and a scale on the body, said scale being so placed asto determine the usual length of a temple piece.

In witness that I claim the foregoing I have hereunto subscribed my namethis 16th day of March, 1910.

ELIZABETH LEE NERO.
